IMPROVEMENT IN ROTARY ENGINES.

Specification forming part of Letters Patent No. H341,164, datedDecember 31, 1872.

To all whom it may concern:

Be it known that I, JAMES M. OoNKLE, of Beaver Falls, in the county ofBeaver and in the State of Pennsylvania, have invented certain new anduseful Improvements in Rotary Engine; and do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing bad to the accompanying drawing and to the letters of referencemarked thereon making a part of this specification.

My present invention is intended as an improvement upon the rotaryengine for which Letters Patent were granted to me July 18, 1571 and itconsists, first, in stationary rings projecting inward from thecylinder-heads, or outward from a stationary center to form rests orsupports for the valves or steam rebut- Inents and, second, in theconstruction and arrangement of the piston or rotary head which revolvesaround said projecting rings or supports.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is a vertical section of my rotary engine; Fig. 2 is an endView of the samewith one of the heads removed; Fig. 3 is a perspectiveview of the interior revolving piston or head; and Fig. 4 is aperspective view of one of the buckets or Valves.

A represents the cylinder with heads B B, said heads havingsubstantially the same passages as described in my patent above referredto. From the inner side of eachhead B extends a ring, 0, inward towardthe center; or in place of these inward-projecting rings I may have astationary center placed inside of the cylinder or outside shell A withprojectin g rings extending each way out to the heads,

in either case said projecting rings forming supports for the valves D Dto rest upon. The valves D D are constructed and placed in the cylinderA in the same manner as in my former patent.

The rotating piston or head is secured to the shaft E, and consists of acentral roller or head, Gr, formed with two cross-bars, H H, on oppositesides, and at the ends of said bars are formed rings I I. These ringsfit in annular recesses around the projecting rings 0 O in the heads BB, and said projecting rings fit within said rings I and the cross-barsH H. The valves or steam rebutments D D, after passing over the drivingpoints or steam-surface of the piston-wheel, rest on the stationarysupports B B, thus creating no friction on the piston-wheel. After thesteam acts on the piston-wheel it exhausts or escapes through theissue-openings a a in the stationary rings 0 (J and out through theregular exhaust.

Having thus fully described my invention, What I claim as new, anddesire to secure by Letters Patent, is-

1. The projecting rings 0 O provided with issue-ports a a and extendinginward from the cylinder-heads or outward from a stationary center,substantially as and for the purposes herein set forth. v

2. The rotary pistonwheel consisting of the central head Gr, cross-barsH H, and rings I I, and attached to the shaft E, substantially as hereinset forth.

In testimony that I claim the foregoing I have hereunto set my hand this8th day of July, 1872.
